A beam collimated light emitting module with a light color mixed chamber includes a light holder, a light source assembly located on the light holder, an optical lens covering the light source assembly, and a reflector. A seal assembly is positioned within the internal cavity to provide a sealed chamber between the axle shaft assembly and the non-rotating spindle. The present invention relates to safety features with respect to attaching a cab to a frame on load bearing vehicles. The central element is adapted to receive the modules on both of the central element sides. The locking spindle assembly has a fire compliant component made of a first material that melts during a fire to prevent operation of the latch assembly with the exterior operator assembly, and has a fire resistant component made of a second material and configured to block the longitudinal bore of the outer spindle to aid in preventing the spread of the fire through the door. The suspension bracket, in one embodiment, may include a base portion, a first tab portion coupled to the base portion, wherein the first tab portion is positioned substantially perpendicular to the base portion, and a second tab portion coupled to the base portion.
